How To Filter Your Household Water (Without A Whole House System)

I recently felt called to filter our household water at all spout points. The desire to do this came seemingly out of nowhere, but it almost felt necessary.

The modern-day toxic load is high, so whatever I can do to minimize my family’s toxic burden (that’s not too complicated or too expensive) seems like a good idea these days.

We’ve drank reverse osmosis water for years, which I am fine with.

But while many of us drink water often, this is not the only time our bodies are exposed to water.

We’re also exposed to water in the shower, in the bath, when we brush our teeth, when we wash our hands and face, and when we do the dishes or water plants.

So while the quality of your drinking water is important, I started to wonder about our other water.

Was it okay to brush our teeth with tap water or take a bath/shower with it? And our hose water – was it okay for my daughter to play with? And wash our pup with? Or were they being exposed to carcinogens and other toxins?

Have I just blindly trusted the quality of our tap water all along?

Enter: the EWG database. I came across it through a friend.

You input your zip code and it lists out the contaminants in your tap water (as well as the potential side effects of the contaminants).

This is ours…

Yikes.

Thankfully I learned of the EWG database shortly after I decided to filter our household water, which was great timing and validation.

If money weren’t a thing, I would love to get a whole house system. However, it’s not in our budget right now to drop thousands of dollars on one. So instead, I figured out a way to filter each individual system (which ended up being loads cheaper than a whole house system).

In this post, I go over how we filter our:

• hose water
• bath water
• shower water
• drinking water
• sink water (both kitchen + bathroom)

Plus how much it cost us to do all of this.

While we eventually plan to get a whole house RO system, this setup works great for us for now.

Hose water

Filtering our hose water was the first thing we did.

Since my daughter occasionally plays with the hose water (plus we use it to wash our dog, Bear), filtering it was important to us. It also seemed like an easy place to start.

I found this filter on Amazon. It filters out chlorine, lead, and other compounds. It’s actually designed to be used by RVers to turn hose water into water that is safe for drinking.

It was super easy to install. You literally unbox the filter, screw one end into your faucet, then screw the hose into the other end.

For a tutorial, check out my Instagram “Water” highlight.

It comes with a set of 4 filters. You’re supposed to change the filter out every 3 months, so this is a year’s supply.

Also, we don’t actively garden, but we do have a few plants. Whether you garden yourself or just have a few plants like us, I’m sure the filtered water is better for them too!

Shower water

For our shower, I chose this dual KDF filter (ASHLEYR for 10% off).

It reduces chloramine, chlorine, fluoride, iron, lead, heavy metals, bacteria, volatile organic compounds (VOCs), PFAS, chemicals, lime, calcium, and disinfectant byproducts.

It also reduces odors, organic waste, trihalomethanes, and common carcinogens such as carbon tetrachloride, chloroform, benzene, and vinylidene chloride.

We purchased one for our master bedroom shower and will be purchasing another for our second shower in a few months. (We just use our master shower for now.)

Installation was straightforward. To see a video of what it looks like installed, check out my Instagram “Water” highlight.

Here is a photo of the shower filter installed.

The filters last 12 months.

Note: This filter is not compatible with Moen shower heads. We had a Moen, so we had to get a new shower head. My husband and I have always wanted a “rain” system, so that’s what I chose. It wasn’t cheap, but it wasn’t horribly expensive either and we both really like it so far! For a video of the system installed, check out my Instagram “Water” highlight.

Bath water

For our bath water, I chose this bath ball filter (ASHLEYR for 5% off). It removes chlorine, chloramines, VOCs, PFAS, THMs, pesticides, sulfur, heavy metals, hydrogen sulfide (“rotten egg” odor), iron oxides (“rust water”), dirt, sediment, and other odors while also balancing pH.

Installation was a breeze. It was up and running in minutes. For a tutorial, check out my Instagram “Water” highlight.

Here is a photo of the bath ball filter installed.

Each bath ball lasts 12 months.

Important note from the product page: “The hardness of your water will determine the performance of the bath ball filter. Hard water has the ability to damage the coating on the chrome bath ball filter. If your water is hard, then we recommend wiping down the bath ball after each use or purchasing the white bath ball for durability against your water.”

I chose the white bath ball for this reason as I did not want to worry about extra maintenance.

If the standard handle doesn’t fit around your faucet, it also comes with a flexible handle (pictured below) that you can bend into whatever shape you want. I have friends who have a tilted faucet with no plug stopper on it, and the flexible handle ended up working for them.

Also, I got a great question from a reader who purchased a bath ball filter. She was concerned about running hot water through it since it’s plastic and wondered if that bothered me.

My thoughts on that:

No, it doesn’t bother me. Would I prefer metal over plastic? Absolutely. But the introduction of the bath ball filter is a net positive to the health of our water overall, so that’s a win for me. If I find another filter that is metal, I will get it when it comes time to replace the filter in a year. But for now, I am excited about this one.

Drinking water

We buy reverse osmosis water from Whole Foods and send it through our Berkey.

This may be a little overkill, but perhaps not with how toxic everything seems to be these days.

The water is basically stripped when it comes out, so we remineralize it with sea salt (ASHLEYR for 15% off) or Trace Minerals.

We also remineralize our dog’s water (using Trace Minerals, not sea salt). If you think about it, there was probably never a point in time where animals drank stripped/filtered water. That’s a modern thing.

The Berkey’s body is stainless steel and the filters remove metals, plastics, chemicals, and other contaminants from water.

They even claim that you can use their filters on things like lake water. You wouldn’t want to do that regularly obviously, but I love having it on hand in case shit hits the fan and we find ourselves in a situation where we would need to do that.

The filters last for years.

And if you need some extra filtration support, Berkey sells these filters specific to fluoride/arsenic reduction that you can add to the system.

For a situation like ours (starting with reverse osmosis water), I think this would be a bit much.

But if tap water was our original source of water, I’d consider getting them.

Update: I decided that putting RO water through the Berkey was a bit much, so we switched to housing our drinking water in this dispenser. The body is glass and it has a stainless steel spout, which is great because every other glass water dispenser I looked at had a plastic spout. The spout feels great/heavy in the hand which makes me think it’s high quality. The dispenser holds 2 gallons.

It also comes with a fruit infuser (which is plastic). I probably won’t use it, but I do randomly crave fruity water so maybe one day I will. It’s cool to have the option.

We used a plastic dispenser for years (before I remembered we had the Berkey recently), and I’m excited to get rid of it! One less plastic thing in our home.

The 5-gallon jugs that we use to get our RO water each week are plastic. I found some super cool stainless steel cans (5-gal and 10-gal options). I am hoping to swap our plastic jugs out for those once our budget allows. And eventually, we won’t need jugs at all once we get a whole house RO system.

Sink water

The last thing we did was filter all of our sink water.

It’s something I never even considered before, but it’s crazy to think that we’ve been brushing our teeth, washing our faces, and doing dishes with carcinogenic water.

It’s a wild (and eye-opening) realization when I write it out like that.

Since we have one kitchen sink and three bathroom sinks, I purchased four of these systems.

The filter reduces PFAS, PFOA/PFOS, lead, chlorine, heavy metals, chemical iṁpurity, sediment, and other large particles.

On the product page, the company lists out a few possible configurations. Connect a filter…

• to the household faucet
• to an exclusive faucet
• directly to the fridge/ice maker/RVs

The “household faucet” route sounded nice, but we’d probably be running so much water through there that we’d have to replace that filter much more often.

So we decided to go the “exclusive faucet” route, which is why I bought four systems – one for each sink.

Installation was straightforward. It took my husband about two hours to install all four.

Each filter lasts two years.

What all of this cost us

Here’s a breakdown of what we purchased to filter our household water:

• One set of hose filters: $30.99 – lasts 12 months
• One shower filter: $199 – lasts 12 months
• One shower head: $104.46 – lasts indefinitely
• One bath filter: $64.95 – lasts 12 months
• One water dispenser: $39.99 – lasts indefinitely
• Four sink filters: $69.99/filter – lasts two years

Here’s the start-up cost breakdown (not including tax + shipping):

• Hose filters: $30.99
• Shower filter: $199 x 10% off with ASHLEYR = $179.10
• Shower head: $104.46
• Bath filter: $64.95 x 5% off with ASHLEYR = $61.70
• Water dispenser: $39.99
• Sink filters: $69.99 x 4 = $279.96

TOTAL = $696.20

Here’s the breakdown of what it costs annually to maintain the system*:

• Hose filters: $30.99
• Shower filter refills: $115 x 10% off with ASHLEYR = $103.50
• Bath filter: $64.95 x 5% off with ASHLEYR = $61.70
• Sink filters: $69.99 X 4 = $279.96/2 (since they last two years) = $139.98

TOTAL = $336.17

This comes out to about $28/month.

*The annual cost breakdown factors in the following considerations:

• filter refills are cheaper than the initial start-up cost for the shower filter,
• the sink filters last two years (not 12 months like the rest of the filters),
• the water dispenser/shower head should not need to be replaced anytime soon.

Final thoughts

I feel better knowing that the water my family uses is much cleaner now.

If you decide to filter your household water, I hope the suggestions in this post were useful.

I took videos of many of the steps explained above and shared them on Instagram Stories. They’re saved in my ​Instagram “Water” highlight​ if you want to reference them.
